Question
A man, after making the first investment, earned a total interest of Rs. 1,09,200 at the end of 3 years. He invested a certain amount at an annual compound interest rate of 20%. At the same time, he invested another sum in two different parts in a scheme. In this scheme, he allocated 40% of the total amount to earn interest at a simple interest rate of (92/3)% per annum, while the remaining portion was invested at a simple interest rate of 20% per annum. Now, if the man had invested the entire amount in a simple interest scheme at a rate of 40% per annum for the same 3-year period, how much more interest would he have earned?
